I had to replace the plugs and that was quite expensive and required a good amount of work. The heat hand did not work and the car ran hot on me one day and the engine shut off and that messed up the head.
I loved my car because it was fast and handled wonderfully. It had excellent start off speed and top speed. I got my Monte Carlo up to 135 on the interstate.
I agree with your ratings, very sporty and reliable car. Mine is also a 95 Z34 very fast and handles excellent with plenty of room for five adults. I would highly recommend this car and would own another in a heart beat.
